Caveat

• Opinions expressed do not represent the
  official Federal Aviation Administration (FAA)
  position and represent solely the opinions of the
  presenter.

3
Systems Issues - Challenges in Complex Systems

• Challenge Areas
• 1. Requirements Issues
• 2. Integration Issues
• 3. Change Management

• No silver bullet for resolution
• No one area is the sole problem
• No area exists in isolation from the others

4
Systems Issues - Challenges in Complex Systems

• Requirements Issues
• Validation build the right system
• Verification ensure correct implementation
• Management across developers, suppliers,
  integrators
• Distinction system, hardware, software
• Implementation reuse and certification

5
Systems Issues - Challenges in Complex Systems

• Integration Issues
• Integration of components
• Inter-component commitments
• Verification of integrated modular avionics

6
Systems Issues - Challenges in Complex Systems

• Change Management
• Impact of change on other components
• Impact on requirements and commitments

7
Systems Issues - Challenges in Complex Systems

• Research Needs

• Means to safely certify systems using COTS

• Means to easily and safely reuse systems/tools
  previously certified/qualified

• Means to validate and verify complex, highly
  integrated systems to ensure requirements are
  complete, correct, correctly implemented,
  consistent, and communicated to affected users

8
Systems Issues - Challenges in Complex Systems

• Roadmap Challenges

• Maximize scarce resources, experience,
  entrepreneurship

• Minimize stove-piping while recognizing and
  respecting proprietary efforts and capitalistic
  system

• Understand and recognize crosscutting impact of
  software issues across disciplines
